S38 0 Sets an optional delay, in seconds, before a forced hang-up and clearing of the Transmit buffer

when DTR drops during an ARQ call. This allows time for a remote modem to acknowledge

receipt of all transmitted data before it is disconnected. The modem immediately hangs up when

DTR drops.

This option only applies to connections terminated by dropping DTR. If the modem receives the

ATH command, it ignores S38 and immediately hangs up.
